Asus ROG Ally 7"

Selling because I'm trying to put the money towards a LeGo 2. Originally purchased from Best Buy, this Ally has been upgraded with the following:

1. 74 Whr battery mod (original battery discarded, used aluminum plate mod from YouTube)
2. 1 TB NVME (2230)
3. Matte screen protector (already installed)
4. Vinyl whole body skin (Gundam themed - already installed)
5. White ergonomic 3D printed grips (black ones broke - price adjusted) - picture coming soon
6. Official ROG Ally soft carrying case
7. Mechanism mount (stuck to custom translucent back plate) + kickstand
8. XG Mobile 4090 with original packaging

I use Bazzite/Windows dual boot, and it's incredible. I don't get as much use out of the 4090 at my desk as I thought I would, so it's another reason I'm selling. Both items are outside of warranty, and the modifications to the Ally void it anyway. I will fully reset the Ally to Windows stock through Asus recovery before shipping.
